Figure 4. Effects of 4 and 8-week dietary supplementation with resveratrol or pinostilbene on motor coordination and spontaneous activity as measured by the challenging beam and cylinder test.
(A) Dietary supplementation for 4 weeks with resveratrol decreased the number of errors made by 24 month old animals. (B) Dietary supplementation for 8 weeks with resveratrol or pinostilbene did not improve motor function of old animals. (C) Dietary supplementation with pinostilbene but not resveratrol increased the number of rears made by middle-aged and old animals.
